Hello, I'm new on gem, so maybe this is very simple to do, I read a PD tutorial on the web, I only want to play a video but just can't make it, here is what I have been doing, if anyone can tell me what I'm doing wrong. the printer tells me this pix_filmDarwin: no method for 'symbol
Here is the patch as the tutorial tells. And just dont work with me.

[gemhead] [create(
l l
l {toggle} [gemwin]
l l
l /[auto $1(
l/
l {bang}
l/[openpanel]
l
[pix_film ]
l l l
l l {bang}
l l
l [unpack 0 0 0]
l l l l
l [0) [0) [0)
l
[pix_texture]
l
[rectangle 4 3]

The file that I want to open is .avi
Greetings

I found what was missing, here I send it if anyone have the same problem, here is how I found the solution.
Now I have other problem, when the video is playing I see that the colors of the video are changing at green flash, does anybody know why it happen?, and how fix it

Thanks

Here is the new patch
